    • Abstract

    Background
    The frequency of detection of peripheral pulmonary mass lesions is rising with increasing availability of radiological imaging. Their aetiology may need to be established, particularly in cases of suspected malignancy. Traditional means of obtaining tissue include CT-guided biopsy, bronchoscopic biopsy, endoscopic ultrasound with fine needle aspiration and surgery. Each modality has potential complications. Endoscopic ultrasound miniprobe (EBUS-MP) is established as a valuable tool, particularly in the staging of early GI tumours. EBUS-MP has been used for qualitative assessment of bronchial structures post lung transplant but data is sparse regarding the role of EBUS-MP sampling of peripheral pulmonary mass lesions. The paper illustrates our experience with this technique to date.

    Methods
    Procedures were carried out in a tertiary respiratory centre over 18 months. Patients were referred for suspected pulmonary malignancy. CT images for each case were reviewed prior to selection. All procedures were undertaken by the same consultant bronchoscopist, assisted by a respiratory trainee. Samples (biopsies / endobronchial brushings / washings) were taken from the identified subsegmental bronchus. Each case was reviewed with respect to diagnostic rate, management, complications and potential alternative non-surgical investigations.

    Results
    45 EBUS-MP procedures were performed on 43 patients. Age range 40 – 87 years (mean 69.2 years +/- 10.8). FEV1 ranged from 0.8L to 3.3L. Lesions from all lobes were targeted. No complications occurred in study population. Figures 1 and 2 show detailed outcomes for EBUS-MP. Figure 1 Figure 2

    Conclusion
    EBUS-MP is a relatively novel technique in bronchoscopy. Our early experience has demonstrated some potential usefulness of the procedure. EBUS-MP allows good visualisation of lesions, can deliver a tissue diagnosis and provide reassurance. No complications have occurred to date. We believe that EBUS-MP sampling may have a role in investigation of peripheral pulmonary mass lesions. In a well selected cohort of patients it appears to be a safe alternative to CT-guided biopsy.
